Hypotensive patients with multisystem injuries involving the chest and pelvis are more likely to have an associated diaphragmatic injury anxiety help order discount hydroxyzine on line. When the blunt injury occurs on the right side, the liver may prevent abdominal visceral from entering the right hemithorax. Bilateral diaphragmatic rupture is much less frequent but, when present, may lead to a delay in diagnosis due to the apparent lack of diaphragmatic elevation on either side. When the chest radiograph does not confirm a diaphragmatic rupture, a number of other studies may be obtained. Thoracoscopy has been used in patients with late manifestations of a previously missed diaphragmatic injury. B, Injection of contrast agent through the nasogastric tube confirms the gastric filling. B, Right chest tube yielded 500 mL blood with continued bleeding of 300 mL during the next hour. The diagnosis of a penetrating injury is usually made at the time of laparotomy performed for the treatment of other organ injuries. B, Two hours later, both hemidiaphragms are elevated, and both costophrenic angles are obfuscated. B, this air bubble increased 1 day later, resulting in reoperation, which demonstrated a missed 4-cm vertical tear of the diaphragm posterior to the left triangular ligament and adjacent to the esophageal foramen. When the perforation occurs along the medial portion of the diaphragm near the esophageal foramen, the herniated viscus may also extend into the pericardium, which makes the diagnosis somewhat more difficult. The decisions regarding resuscitation and prioritization of specific organ injury treatment are discussed elsewhere in this text. Most patients with grade I injury (contusion or hematoma) are diagnosed at the time of laparotomy or thoracotomy performed for some other reason. The surgeon should make sure that the hematoma or contusion is not hiding a full-thickness perforation. When diagnosed by laparoscopy, minor perforations may be repaired through the scope. The type of suture used for closure of diaphragmatic perforations varies according to surgical preference; the authors prefer 2-0 or 1-0 absorbable polyglycolic sutures. When the perforation is posterior, suture placement may be facilitated by hooking the diaphragm through the perforation with a long right-angle clamp, thus, exposing the perforation for suture placement. Once the perforation is exposed, the initial placement of strategic sutures designed to reapproximate the irregular borders helps with the subsequent closure. The authors prefer to use interrupted 1-0 absorbable suture for approximation along the irregular borders followed by the placement of running 1-0 absorbable sutures for the definitive closure. The authors prefer a running 0 absorbable polyglycolic suture for most minor injuries. This is reinforced with strategically placed interrupted sutures for major injuries. These larger injuries usually are associated with herniation of abdominal viscera into the left hemithorax. Classically, the stomach, spleen, and colon are herniated; omentum and small bowel may also be in the thorax. If the viscera resist gentle traction, the surgeon should place a hand within the thorax, cup the spleen, and gently push the viscera into the peritoneal cavity. This precaution protects the herniated spleen which, surprisingly, is seldom injured in these patients. The diaphragm has significant redundancy in the relaxed state, so this approximation can be achieved without tension. Although there will be decreased excursion of the repaired hemidiaphragm after primary closure in this setting, there is seldom long-term impairment. When approximation of ragged borders is difficult, a modified Z-plasty is helpful. In theory, the incisions made in creating the Z-plasty should be radial, extending from the medial plane to the periphery, thus preserving the branches of the phrenic nerve; however, the long-term result of successful approximation of a viable diaphragm is almost always excellent, even when branches of the phrenic nerve are severed. When repairing large defects, one should reapproximate the midportions of the defect, so that the lateral portions can be accurately reapposed without creating a dog-ear type of closure. The grade V diaphragmatic injury with tissue loss exceeding 25 cm presents a major surgical challenge. Many of these large defects with major tissue loss, however, can be closed primarily if the adjacent chest cage and abdominal wall are intact. When the central defect precludes a tension-free approximation, even in the relaxed state, the peripheral diaphragmatic attachments can be severed anteriorly, laterally, and posteriorly from their costal origins so that the defect can be closed and the diaphragmatic edges reattached two or three interspaces more cephalad. This permits a generous advancement of healthy tissue and allows a tension-free primary closure. Patients sustaining blunt diaphragmatic rupture often have associated injury to the liver, spleen, or more importantly, the underlying lung. The association of multiple rib fractures and pulmonary contusion often causes respiratory compromise and prolonged ventilatory support; a fatal outcome is not unusual. The collective review by Asensio and coworkers described an overall mortality rate of 4. The lower mortality rate is noted in patients treated for penetrating wounds; the higher mortality rate, reported by Boulanger and coworkers, reflected treated patients with associated injury to rib cage, lung, and brain. During this same interval, the authors observed a mortality rate of well under 4% in patients treated with penetrating diaphragmatic wounds.

The eye can be examined from the cornea to the optic nerve anxiety 9 months postpartum cheap hydroxyzine 25 mg line, through closed eyelids with virtually no pressure exerted on the globe. In the presence of hyphema or vitreous hemorrhage, the posterior pole of the eye may be difficult to view, in which case an ultrasound examination may allow thorough evaluation. These cases are typically occult with no external signs of rupture and normal intraocular pressure. Moreover, with a foreign body that is adjacent to the scleral wall, ultrasound is able to determine whether it lies just inside or outside the globe. Chemical and thermal burns are often associated with open eye injuries or can occur in isolation. The mainstay of treatment is copious irrigation and treatment with topical steroids and antibiotics. However, in the presence of an open globe, repair of the rupture is of primary importance and should then be followed by management of the chemical and thermal injury. Orbital computed tomography scan reveals that foreign body does not extend beyond the anterior chamber (arrows). Note that the conjunctiva is Vision worse than 20/400 Intraocular pressure in nontraumatized eye > intraocular pressure in traumatized eye Hyphema Afferent pupillary defect Vitreous hemorrhage 88 71 47 61 elevated and boggy, not flat as seen with subconjunctival hemorrhage, a benign condition. Between each liter of irrigation, the pH should be reassessed and irrigation continued until the pH becomes neutral. The upper and lower fornices should be swept with a cotton swab for crystallized particles if the pH does not neutralize and lid eversion may be required to remove the particles. Acidic compounds rarely penetrate into the anterior chamber to cause further damage. On the other hand, bases have the capacity to saponify the superficial lipophilic layers of the cornea and readily penetrate the deeper tissues, frequently causing damage to the intraocular structures and leading to glaucoma and cataract. The rule of thumb in these cases is that the quieter the appearance after a chemical burn, the worse the prognosis. This is due to the fact that the vasculature of the ocular surface has been obliterated and the eye will be deceptively blanched in appearance. These cases require extensive ocular surface reconstruction, glaucoma surgery, and transplantation of the cornea to regain visual function. Aggressive irrigation within the first few minutes and hours has the most profound impact on the final outcome. Treatment with topical antibiotics and steroids in the first few days is of paramount importance. This is often initiated in the emergency/trauma setting and can be done well before the patient is seen by an eye care provider. One of the goals of this process was to promote the use of trauma-specific terminology in describing eye injuries. Pieramici et al studied the prognostic significance of this system for classifying mechanical injuries of the eye. These variables were chosen because they have been shown to be prognostic of visual outcome, and they can be assessed clinically on initial examination or during the initial surgical procedure. C, Transverse B-scan view through area of scleral rupture shows vitreous incarcerated into scleral wound and retinal detachment (R). However, as previously mentioned, with an obvious rupture, the trauma surgeons and emergency physicians are urged to cover the eye with a Fox shield and allow the trained ophthalmologist to perform the remainder of the examination. With a keen understanding of the findings of closed and open globe injuries, the trauma surgeons and emergency physicians should be able to appropriately categorize these eye injuries and aid the eye care provider in making effective medical and surgical management decisions. If the patient has no complaints of diplopia and very little restriction of ocular motility, surgical intervention is not indicated and the patient can be observed weekly. A, Axial computed tomography scan shows spherical foreign body (straight white arrow) in vicinity of posterior ocular wall. The patient has a total corneal epithelial defect as seen with fluorescein stain and cobalt blue light. Despite aggressive management, the patient has a total burn of the ocular surface with extensive inflammation and obliteration of the fornices. Fractures of the orbital roof, fractures associated with cerebrospinal fluid rhinorrhea, and orbital fractures associated with intracranial hemorrhage require neurosurgical evaluation, and often are repaired collaboratively by neurosurgery and ophthalmology. Performing a lateral canthotomy and cantholysis requires application of local anesthetic and the use of toothed forceps and straight scissors. The lateral orbital rim is palpated and the tissue extending from the lateral canthal angle to the orbital rim is cut in a vertical fashion, splitting the upper and lower connection of the eyelids. The lower lid is grasped with the forceps and tension is placed on the canthal tendon. Many physicians take a step-wise approach to performing this procedure by cutting the lower canthal tendon and remeasuring the intraocular pressure. If the pressure normalizes by this step alone, cutting the upper canthal tendon can be deferred. On completion of this procedure, there is often a release of blood from the retrobulbar space and the eye becomes even more proptotic. However, the result should be the lowering of intraocular pressure and reestablishment of normal blood flow to the eye. Central retinal artery occlusion, optic nerve avulsion, and damage to the nerve within the optic canal (fracture or compression within the canal) are less amenable to medical or surgical intervention.

Noninfectious factors can also initiate severe inflammatory responses that may culminate in multiple organ failure and death anxiety girl cartoon order hydroxyzine with a mastercard. Hepatic parenchymal healing appears to be virtually complete at 6 to 8 weeks after injury. In most large series of blunt hepatic injuries, associated brain injuries account for most (60% to 70%) of the deaths. Over the past 2 decades, the mortality rate of complex hepatic injuries has decreased, predominantly because of a reduction in deaths from liver hemorrhage. Successful embolization of the lesion usually permits continued nonoperative management. Should the patient under observation become hemodynamically unstable or develop peritoneal signs, operative intervention should be undertaken without the slightest hesitation. When the liver injury requires operative intervention, four essential maneuvers should be kept in mind: (1) manual compression of the injury, (2) resuscitation, (3) assessment of the injury, and (4) the Pringle maneuver (inflow occlusion). These maneuvers can be lifesaving, even in the hands of those with limited experience in this area. Most of these patients are hemodynamically unstable, have multiple associated injuries, require massive blood transfusions, and have a significant mortality rate. Resumption of Normal Activities Dulchavsky et al demonstrated in experimental models that hepatic wound bursting strength at 3 weeks after injury was comparable and often exceeded wound bursting strength of normal hepatic parenchyma. Moreover, healing by secondary intention resulted in wound bursting strength equal or greater than hepatorrhaphy or hepatorrhaphy and omental packing at 3 and 6 weeks.

Wisner and requires the same management algorithm used in other types of splenic trauma. The Greeks and Romans believed that the spleen played a role in filtering the humors of the body, mirroring some of our modern concepts. During the middle of the last millennium, the Thuggee cult, who worshipped Kali, a Hindu goddess of destruction, were professional assassins, and the act of murder for hire was an act of worship for their goddess. They were most famous for their use of the noose, but also targeted the left upper quadrant where the spleen, often fragile and swollen from malaria, lay. A well-placed blow leading to splenic rupture in the absence of transfusions and modern surgery often proved fatal. As our understanding of splenic injury has increased, our management of splenic injuries has evolved. Thus, we have steadily moved away from routine aggressive operative management toward nonoperative management. With this evolution, it is still important to keep in mind that splenic injuries can be deadly and patients with damage to the spleen can bleed to death just as they did in the time of the Thuggee. Splenic injuries occur via three mechanisms: penetrating, blunt, and indirect trauma. For penetrating trauma, retrospective reviews of two large centers, Grady Memorial Hospital and Ben Taub General Hospital, showed the incidence of splenic injury from abdominal gunshot wounds to be 7% to 9%, far less than for the hollow organs and the liver. Blunt splenic injuries can bleed either immediately or on a delayed basis, a phenomenon of obvious importance in patients treated nonoperatively. The incidence of delayed bleeding, leading to failure of nonoperative therapy, varies depending on the grade of the injury. One hypothesis for the pathophysiology leading to delayed bleeding is that as subcapsular clot breaks down several days after injury into its component parts, the number of osmotically active particles in the area increases and draws more fluid into the area of injury. The resultant increase in size of the area then exceeds the tensile strength of the capsule, leading to rupture and renewed bleeding. Even without being trapped under the capsule of the spleen, the inflammation and fibrinolysis in and around the healing injury and clot may weaken the clot enough to result in renewed hemorrhage. A third mechanism of injury to the spleen is indirect trauma, specifically during colonoscopy. This is a subtle, frequently unrecognized and underreported complication of routine colonoscopy. A particularly important general comment relative to initial resuscitation is that it is important to recognize refractory shock early and treat it with an appropriate operative response. In the initial history taking, it is important to note any previous operations the patient has undergone, especially a history of splenectomy. History of direct blows to the lower left chest or left upper abdomen, with concomitant pain, may engender suspicion for splenic injury.

It is usually the result of direct anterior-posterior impacts low on the midface anxiety after eating buy hydroxyzine 25 mg mastercard, producing fractures of the vertical and horizontal buttresses of the midface. This fracture often begins at the nasal bones and crosses the frontal process of the maxilla and lacrimal bones. It then descends through the floor of the orbit, infraorbital rim, and lateral maxillary sinus wall, extending posteriorly through the pterygoid plates. The resulting fracture creates a pyramidal fracture of the inferior facial segment, which is separated from the remaining craniofacial skeleton. Similarly, as seen in Le Fort I fractures, the fracture traverses the nasal septum, posterior maxillary walls, and pterygoid plates. This fracture pattern is the most common pattern of fracture, occurring in almost 60% of all cases. Such a fracture pattern is often caused by oblique forces to the vertical buttress and is the most rare of all three fracture patterns. It is commonly seen in high-velocity impact and associated with significant comminution and intracranial injury. Although many fractures do not actually follow this strict classification scheme, it does prove a useful tool in assisting with communicating the patient workup and surgical management. Often they demonstrate characteristics of several Le Fort injuries on opposing sides of the bony facial skeleton. Of all facial fractures, Le Fort fractures are seen in approximately 10% to 20% of patients. This pattern of facial fracture is most commonly seen after motor vehicle accident, interpersonal violence, or falls from height. With an expanding elderly population, there is an expected increase in the number of Le Fort facial fractures in the older population. They generally have a proportionately larger mandible and frontal bone, combined with more flexible facial bones, undeveloped maxillary sinuses, and dentition that has not yet erupted, all of which prevent children from such fracture patterns. Le Fort fractures are often associated with other types of head and neck injuries, including intracranial, ophthalmologic, and neck injuries. Therefore, it is vital that the intial workup and diagnostic tests evaluate all aspects of the head and neck if a Le Fort fracture is identified. Although it is often difficult in the trauma setting, the surgeon or emergency room physician must perform a thorough evaluation of facial injury after adequate life resuscitating measures have been performed. Often bleeding is secondary to mucosal tear of the septal, nasal, or sinus mucosa. Once stable, premorbid dental occlusion and previous history of dental trauma are important to ascertain. A detailed ophthalmologic history is also vital to evaluation for any acute changes in vision. Examination should also include inspection and palpation of the entire facial skeleton, evaluating for mobility of facial structures. Malocclusion is often seen in which a displaced maxilla may lead to premature contact or an open bite deformity. Often forces of midface trauma cause a posterior displacement of the maxilla along the skull base. If the injury has extended to the bony orbit, ecchymosis or an abnormal globe position may be encountered. This can be evaluated by using the thumb and forefinger to grasp the premaxilla while the other hand stabilizes the infraorbital rims. Special attention should be made on imaging through the orbits and the base of skull, as intracranial injury may alter the surgical algorithm. Surgical management of Le Fort fractures is focused on restoration of function as well as aesthetic aspects of facial symmetry. Reestablishment of facial height and facial projection and reconstitution of premorbid dental occlusion are the primary goals of surgical repair. It was previously believed that repair of Le Fort fractures should wait for resolution of soft tissue edema, allowing a better evaluation of surgical landmarks and a better postoperative reduction. However, it is now felt that early surgical intervention with open reduction and internal fixation allows for a more precise repair before there is any bony resorption or fibrous ingrowth, which is often seen with a delayed repair. Some authors report earlier return to function, decreased infection rate, decreased scarring, and fewer postoperative complications with an immediate repair. Midfacial bones can be exposed by way of concealed surgical incision through a combination of intraoral, transconjunctival, bicoronal, or midface degloving in order to reduce all of the fractured buttresses. Choice of incision is determined by the location and extent of the fracture sites. Once the fractures are adequately reduced, rigid fixation using a combination of low- and high-profile titanium plating systems can be implemented. Patients are also placed into intermaxillary fixation with arch bars with interdental wiring in order to limit the degree of motion and compression on the reduced fracture line. Complications of midface fractures are often divided into bony and soft tissue defects, which may result in either functional or aesthetic challenges. Bony complications include malocclusion secondary to a combination of delayed union, malunion, nonunion, or fibrous union.

The optimal timing for reimaging anxiety symptoms without anxiety 10 mg hydroxyzine buy amex, however, remains to be established as the 7- to 10-day delay is based on the risk of repeat angiography within the first 5 days after injury. Specifically, half of patients become symptomatic greater than 12 hours after injury. Consequently, it became evident that there is a therapeutic window of opportunity. Currently, in centers with a comprehensive screening approach, the screening yield is over 30% in high-risk populations. Such a location makes the standard vascular repair approaches, including reconstruction or thrombectomy, challenging if not impossible. In these studies, up to 45% of patients achieved good neurologic status, and anticoagulation therapy was independently associated with survival and improvement in neurologic outcome. Subsequently, intravenous heparin was thought to be the treatment of choice for those asymptomatic patients with blunt injuries. Currently, anticoagulation with systemic heparin is initiated using a continuous infusion of heparin at 15 U/kg/ hour, without a loading dose; heparin drips are titrated to achieve a partial thromboplastin time of 40 to 50 seconds. For patients with a contraindication to heparin, antiplatelet agents (currently aspirin 325 mg/day) have been administered. Antithrombotic therapy is not started in patients with closed head injury or intraparenchymal hemorrhage without agreement from the neurosurgery service. Antithrombotic therapy in patients with significant solid organ injuries or a complex pelvic fracture with associated retroperitoneal hematoma is typically not started until at least 24 hours of physiologic stability without transfusion requirements. Currently there is controversy regarding the ideal antithrombotic therapy for any type of arterial disease-anticoagulation versus antiplatelet agents. A retrospective study by Chimowitz et al indicated that warfarin is superior in patients with vertebrobasilar occlusive disease, but a more recent prospective double-blind comparison by the same authors demonstrated that aspirin is the therapy of choice for patients with symptomatic intracranial atherosclerotic arterial stenosis, due to equivalent stroke prevention rates as warfarin, but decreased hemorrhagic complications. A recent review of vertebrobasilar disease supported the use of antiplatelet agents in patients with arterial stenosis but warfarin in patients with severe, flow-limiting lesions or dissections. Although the optimal regimen remains unanswered, there appears to be equivalence between anticoagulation and antiplatelet medications in both prevention of stroke as well as healing/progression rates of individual injuries. Our group advocates use of intravenous heparin in the acutely injured patient with transition to antiplatelet agents at discharge owing to easier reversal with fresh frozen plasma should a bleeding complication occur. Although the optimal regimen remains unanswered, there appears to be equivalence between the two therapies (anticoagulation and antiplatelet agents) with regard to stroke rate. Following initiation of antithrombotics, treatment is empirically continued for 6 months based on the assumption of reendothelialization. Comprehensive long-term follow-up beyond the acute hospitalization has not been reported in the literature, as is true in most trauma population studies. Routine stenting entails increased costs and potential risk for stroke and does not appear to add benefit. In our practice, intravascular stents are reserved for the rare patient with symptomatology due to narrowing or a markedly enlarging pseudoaneurysm. Patients with persistent injuries on repeat imaging are often treated with lifelong aspirin, although, as is true for any longterm therapy, the risks of treatment should be discussed with the patient. A less studied variable is the impact of neurologic morbidity on the need for prolonged acute patient care. Such prolonged acute patient care increases costs to the patient, insurance companies, and ultimately to society. Although the role of carotid stents for atherosclerotic disease is being explored with randomized, wellcontrolled trials, the indication for percutaneous intervention for traumatic injuries is less well defined. Carotid stents have been used in patients with blunt injury with persistent pseudoaneurysms because of the concern for subsequent embolization or rupture. In theory, the uncovered carotid stent acts as a filter to trap any thrombus within the pseudoaneurysm, thereby preventing embolization and stroke. The stent may also decrease flow into the pseudoaneurysm by increasing laminar flow within the stented portion of the carotid lumen itself. Decreasing flow into the aneurysmal sac may then reduce any egress of blood from the sac, which in turn may reduce turbulence within the lumen. There are anecdotal reports of carotid pseudoaneurysm rupture, particularly in the petrous portion of the canal leading to epistaxis, but we have not observed this event. However, aside from isolated cases, few other reports of late events are evident in the literature. Thus, it is difficult to confidently state either the true healing rate of these injuries or the risk of rupture or delayed embolic stroke. Several reports advocate the use of percutaneous angioplasty and stenting of carotid injuries. Although the majority appears to have patency of the stented carotid artery documented in follow-up radiographic evaluation, several cases of carotid artery occlusion following stent placement have been reported. An early evaluation of the use of endovascular techniques, prior to the routine use of cerebral protection devices and the recommendation for antiplatelet treatment following stent placement indicated a significant stroke and carotid occlusion rate associated with carotid stents placed in acutely injured vessels. Without long-term follow-up of patients with traumatic pseudoaneurysms treated solely with antithrombotics it is difficult to determine which treatment modality, stenting versus medical management, is optimal. Berne S tructural mobility and elasticity are characteristics of the upper airway that make injury to these structures infrequent. These injuries are frequently lethal, which explains their higher reported occurrence in autopsy series.

The multidisciplinary team caring for trauma patients must make every effort to prevent heat loss and help to correct hypothermia anxiety care plan 10 mg hydroxyzine order otc. More than 25% of trauma patients exhibit overt coagulopathy at the time of admission and it is associated with a threefold increase in mortality risk. The causes of coagulopathy in patients with severe trauma are multifactorial, including consumption and dilution of platelets and coagulation factors, as well as dysfunction of platelets and the coagulation system. Clinical coagulopathy occurs because of hypothermia, platelet and coagulation factor dysfunction that occurs at low temperatures, activation of the fibrinolytic system, and hemodilution following massive resuscitation. Platelet dysfunction is secondary to the imbalance between thromboxane and prostacyclin that occurs in a hypothermic state. The predominant physiologic defect resulting from repetitive and persistent bouts of hypoperfusion is metabolic acidosis. Anaerobic metabolism starts when the shock stage of hypoperfusion is prolonged, leading to the production of lactate. Acidosis decreases myocardial contractility, cardiac output, functional clotting, and clot strength. Acidosis also worsens as a result of multiple transfusions, the use of vasopressors, aortic cross-clamping, and impaired myocardial performance. It is clear that a complex relationship exists among acidosis, hypothermia, and coagulopathy, and each factor compounds the other, leading to a high mortality rate once this cycle ensues and cannot be interrupted. Exsanguination is second only to neurologic injury among causes of fatality after trauma. Certain conditions and complexes of injuries require damage control to prevent exsanguination. This article will describe validated indicators that can be used both preoperatively and intraoperatively to improve outcomes. This article will also outline current guidelines for the institution of damage control in trauma patients. Emphasis is placed on the current indications for damage control as defined by key studies. Awareness of these guidelines can improve outcomes after major intraabdominal injuries and hemorrhage and also assist in the management of one of the well-known sequelae of damage control, the posttraumatic open abdomen. The principles of damage control surgery defied the traditional surgical teaching of definitive operative intervention and were slow to be adopted. Currently, damage control techniques developed by trauma surgeons have been used successfully to manage traumatic thoracic, abdominal, extremity, and peripheral vascular injuries. In addition, damage control surgery has been extrapolated for use in general, vascular, cardiac, urologic, and orthopedic surgery. In 1983, Stone and associates were first to describe the "bailout" approach of staged surgical procedures for severely injured patients. This approach emerged after their observation that early death following trauma was associated with severe metabolic and physiologic derangements following severe exsanguinating injuries. Profound shock along with major blood loss initiates the cycle of hypothermia, acidosis, and coagulopathy. It was at this time that hypothermia, acidosis, and coagulopathy were described as the "trauma triangle of death" or the "bloody vicious cycle. Coagulopathy, acidosis, and hypothermia make the prolonged and definitive operative management of trauma patients dangerous. This new approach, now called "damage control," describes the operative phase as multiphasic, in which reoperation occurs after correcting physiologic abnormalities. In this study, 17 patients underwent the bailout procedure, which included an initial laparotomy, followed by packing in patients with an observed clinical coagulopathy, and then completion of the surgical procedure once the coagulopathy was improved. The authors reported a survival rate of 77% in a very small subgroup of patients with major vascular injury and two or more physical injuries. Morris et al described 107 patients who underwent staged laparotomy and abdominal packing. Similarly, Moore described a progressive coagulopathy as the most compelling reason for staged laparotomy. It was postulated that the ability to predict the onset of coagulopathy would have significant implications for instituting damage control. No single model has been able to accurately predict the timing for institution of damage control. To define the patient at greatest risk for exsanguination and death, one must determine the threshold levels of pH, temperature, and highest estimated level of blood loss. Therefore, in an attempt to institute the development of intraoperative guidelines for "damage control/bailout," Asensio first retrospectively evaluated 548 patients over 6 years who were admitted to a large urban trauma center with the diagnosis of exsanguination. Overall, 449 patients survived to arrive in the operating room with some signs of life, and 281 patients died; 37% of these patients survived damage control. Table 1 shows the objective intraoperative parameters developed to predict outcome and provide guidelines on when to institute damage control based on these findings. One of the natural sequelae in patients surviving damage control is an open abdomen. These guidelines were prospectively validated in a series of 139 patients who underwent damage control and had posttraumatic open abdomen. This study consisted of two groups of patients: 86 patients studied retrospectively prior to instituting the guidelines, and 53 patients studied prospectively after instituting the guidelines. Another significant finding in this study was that 93% of patients were able to undergo definitive abdominal closure in their hospital stay as compared with the historic 22%.

The first level of concern is for patients who have a drinking problem that can be described as "risky" or "hazardous anxiety symptoms how to stop it hydroxyzine 25 mg purchase mastercard. In the United States, this amount has been defined as more than 7 drinks per week or more than 3 drinks on any one occasion for women, or more than 14 drinks per week or more than 4 on any one occasion for men. Most people will be legally intoxicated if they exceed these levels, are unable to legally or safely drive, and are at risk of acute injury or acute medical problems. Intake greater than the recommended weekly limits, over time, is associated with the development of chronic alcoholrelated medical problems. Further along on the severity continuum are patients who meet diagnostic criteria for alcohol abuse. Abuse is defined as a pattern of repeated consequences involving health, relationships, employment, financial, or legal status that occur as a result of excessive alcohol intake. They generally do not need formal treatment, but appropriate interventions provided by physicians, nurses, and trained nonmedical staff can help these patients reduce or control their intake. Alcohol dependence is present in patients who have experienced repeated consequences, but also experience loss of control, craving, and symptoms of withdrawal upon cessation of alcohol intake due to addiction. These patients are generally more difficult to treat, and attention by a specialist with training in management of addictive diseases is generally indicated and should be achieved by making a referral to a private or publicly funded treatment center. The Institute of Medicine has recommended using the term "alcohol use" "or alcohol misuse" as a more comprehensive term to describe patients with any type of abnormal drinking pattern. Although there is a scarcity of treatment resources, patients with less severe problems who are not alcohol dependent are responsible for the greatest proportion of the societal burden by alcohol use, including car crashes and traumatic injuries. Patients with severe dependence have a disproportionate share of alcoholrelated consequences, and are at higher risk. However, most alcohol-related injuries occur in patients with mild to moderate problems because such patients constitute the greatest proportion of problem drinkers. In a demonstration project in six states and one tribal nation, screening and brief interventions were provided in trauma centers, in-patient medical and surgical wards, emergency departments, and primary care out-patient settings. This finding is consistent with smaller studies that suggest that nearly 1 out 4 people who receive health care use alcohol or drugs in ways that adversely affect health. The remaining 19% with a positive screen met criteria for a brief intervention only. Therefore, most patients with a positive screen for alcohol or drug misuse (84%) can be managed within health care settings such as trauma centers with brief interventions that are easily adopted, and that have proven efficacy and cost-effectiveness in nondependent patients with substance use problems. Patients with an alcohol use problem may not seek treatment for their problem, but they often receive treatment for medical conditions caused by their alcohol use. Injuries are the most common medical condition for which patients with an alcohol use disorder receive medical attention. A recent analysis of 12 randomized brief intervention trials, each of which was limited to one session and consisted of less than 1 hour of motivational counseling, demonstrated that brief interventions were associated with a reduction in hospital admission, use of emergency department and trauma center resources, and medical costs. A randomized, prospective trial of brief interventions in injured adolescents demonstrated significant reductions in drinking and driving, moving violations, and alcohol-related problems, and a greater than 50% reduction in alcohol-related injuries. In a prospective, randomized trial conducted on adult trauma patients, at 1-year follow-up the intervention group decreased their alcohol intake by 22 drinks per week, compared to a 2-drink reduction in the conventional care group. There was a 47% reduction in new injuries requiring treatment in the emergency department, and a 48% reduction in injuries requiring hospital admission in the intervention group patients with up to 3 years follow-up. A recent cost-benefit analysis demonstrated a savings in direct injury-related medical costs of nearly $4 for every dollar invested on screening and intervention programs conducted in trauma centers. A randomized clinical trial conducted in an inner city teaching hospital compared brief interventions for cocaine and heroine use with standard care. At six months follow-up, hair was sampled for radioactive immunoassay to detect drug use. The intervention group had a greater than 50% increase in abstinence rate, and cocaine levels in the hair were reduced by 29% in the intervention group, compared to 4% in control subjects. A screening instrument was used to classify the severity of the alcohol or drug use problem and determine need for a brief intervention, brief treatment (four intervention sessions), or a referral to specialty treatment. The majority of cases were mild and only required a single brief intervention (15. Those who were referred to treatment reported improvements in general health, mental health, employment, housing status, and criminal behavior (P <. The findings were comparable across all six states, and across gender, race, ethnic, and age subgroups. The provision of screening and brief interventions is consistent with the scope, mission, and responsibilities of trauma centers, and capitalizes on the effects of the recent major injury to stimulate and motivate patients to cease or reduce alcohol use. Trauma centers currently provide a variety of rehabilitative services, including physical and occupational therapy, nutrition services, and speech therapy. Resource allocation and staffing patterns should reflect the fact that the form of rehabilitative therapy most likely to be needed by a trauma patient, and the one most likely to keep them from being injured repeatedly, is one that addresses their substance misuse. Recognizing this, the Committee on Trauma of the American College of Surgeons, in the 2006 edition of its document on optimal resources for the care of trauma patients, has deemed the ability to screen for alcohol problems and the provision of brief interventions to patients who screen positive an essential service required to attain verification as a Level I trauma center. This is a major step toward raising the level of awareness of the importance and efficacy of treatment for alcohol use disorders in acute medical settings. It is the first time in the history of health care in the United States that an organization with the ability to set authoritative national standards has ever required any type of substance use counseling in health care. Screening for Alcohol and Drug Problems Reliance on clinical judgment alone to detect alcohol problems has poor sensitivity and specificity, and is subject to discriminatory bias. A study that examined the ability of trauma center staff to detect alcohol use disorders found that physicians and nurses were unable to detect intoxication in one third of significantly injured patients, and they failed to identify more than half of the patients who screened positive for an alcohol problem. This method has a sensitivity and specificity that is similar to more extended questionnaire formats. Because the definition of unhealthy alcohol use in a male is drinking 4 or more drinks on a single occasion, or drinking more than 14 drinks in a week, the clinician can ask the question, "In the past 6 months have you ever drank 4 or more drinks on a single drinking occasion This same question can be modified for women by asking if they have consumed more than 3 drinks in a day.

Muntasir, 23 years: Secondary hemorrhage following operative management of pancreatic trauma may occur in 5% to 10% of patients. He also emphasized analgesia as a potent supplemental therapy in the clinical management of pulmonary injury.

Fabio, 36 years: B, Gram stain of peripheral blood smear from a nonhuman primate infected with Bacillus anthracis, Ames strain. Initial care of obvious injuries includes control of bleeding with pressure dressings, splinting unstable injuries in an acceptable position, and urgent identification and treatment of arterial occlusion.

Zuben, 58 years: One could argue that as the economy becomes globalized, it will be important to have worldwide standards for trauma management and peer review. Esophageal identification is facilitated by the prior insertion of a nasogastric tube.

Aidan, 33 years: These are technically challenging surgical situations, and several technical points can help reduce complications: prevent aspiration by isolating the affected lung prior to posterolateral positioning; expose the main pulmonary artery early in the case so that should hemorrhage result control can be achieved; place a nasogastric tube or esophagoscope in the esophagus because the anatomy may be obliterated; and refrain from resecting small abscesses (<2 cm) that are in otherwise viable parenchyma. The authors have recently used commercially made fibrin sealants to seal complex ventricular injuries.

Jens, 37 years: The ranking medical caregiver must establish communications, ascertain the risk of additional threat to the immediate area, and in addition to providing first aid to those most in need, attempt to 38. This can only occur if the patient remains hemodynamically stable as extrinsic pressure on the inferior vena cava would only exacerbate preexisting hypotension.

Ugolf, 47 years: In this article, we will review the pertinent anatomic considerations of both the abdomen and retroperitoneum. Guidelines Various guidelines for the management of brain-injured patients have enjoyed widespread circulation.

Eusebio, 60 years: Similarly, in 1966, he advocated the use of immediate cardiorrhaphy in the emergency room and setting up an instrument tray; he was also the first to successfully perform this procedure. Operative repair results in markedly reduced pain, improves cosmesis, and improved pulmonary function in patients with overlapping sternal fractures.

Will, 32 years: Disability is a significant problem in trauma patients, and is an important outcome measure for quality improvement processes. They may also require a bypass or interposition graft either with an autogenous reverse saphenous vein graft or with a prosthetic graft.

Hanson, 45 years: The majority of these patients respond to supportive care consisting of analgesics and pulmonary toilet. Yes No Maternal evaluation and treatment Continue maternal evaluation and treatment Consider tocolytics Consider C-section Observation (minimum 4 hours) Radiographic Examination There are three phases of radiation damage related to gestational age of the fetus.

Elber, 22 years: Increased understanding of the causes of death after injury suggests that truncal hemorrhage represents a major cause of potentially preventable death. Most patients with grade I injury (contusion or hematoma) are diagnosed at the time of laparotomy or thoracotomy performed for some other reason.

Peer, 59 years: Several factors contribute to this diagnostic delay including the uncommon occurrence of these injuries. Although highvelocity weapons do impart greater force to the involved tissue, the amount of tissue injury and cavitation will depend more on the properties of the projectile (jacketing, deformities, amount of spin and yaw, and the trajectory capabilities of the missile) than the velocity.

Tempeck, 62 years: This response suggests spontaneous reduction of bleeding due to inherent hemostatic mechanisms and may validate use of this resuscitation strategy in certain scenarios of uncontrolled hemorrhage. Because of the dual blood supply of the spleen though its hilum and also through the short gastric vessels, it is possible to divide the short gastric vessels without compromising splenic viability.

Diego, 34 years: Projectiles typically create a tract or cavity as they travel through tissue, producing primary injury by mechanical disruption and laceration. Several reduction techniques have been described but they all involve correcting the medial-lateral displacement, followed by longitudinal traction and flexion of the forearm.

Dennis, 44 years: A normal intercanthal distance is 30 to 35 mm, which equates to one half of the interpupillary distance or is equal to the alar base of the nose. An experienced interventional radiologist will usually have little difficulty in selectively catheterizing and embolizing the injured vessel, most often with stainless steel coils rather than Gelfoam to achieve the most dependable and permanent embolization.

Orknarok, 27 years: There is growing interest in creation of a large international prospectively created database, including collection of neuropsychological and other prespecified outcome measures, to enable performance of comparative effectiveness studies. The International Classification of Diseases is one taxonomy that is widely used to describe injury.

Dimitar, 21 years: A simple pneumothorax is a collection of air arising from leakage of air from an injured lung into the pleural space. By the age of 40, rotator cuff tear becomes more common than ligamentous injury, and recurrence becomes infrequent.

Seruk, 53 years: The authors also reported the specific location of these injuries: left lower lobe, 40%; left upper lobe, 21%; right middle lobe, 19%; right lower lobe, 11%; lingula, 5%; and right upper lobe, 5%. Therefore, the use of a buttress often enhances healing without fistula development.
